Yes, this should work... > My ISP provides IP through DHCP; NOW the issue is how all the three > machines will get different IP's (Oops I forgot its DHCP). Give your MAC addresses to your ISP team.

Yes they can ofcourse restrict the number of IP's a client can use at their end using a properly configured firewall. > Will I get reasonable speed using this topology? If ISP connection is to a server at ur end and and all ur internal machine is going via ur server then ur onto a shared bandwidth, ur ISP may be providing bandwidth for one machine only. Else if you are getting IP's for all ur internal machine from ur ISP most probably u'll be under a shared bandwidth. Request ur ISP to increase the banwidth on per IP basis assigned at ur end. Usaully we are acheiving this task using CBQ. >Also, I > want to know what crossover connection is and when it is required in a > network. There are totally 8 points or pins or lines (I don't know how to define that :( ) for data transmission between devices. Among them , in sequence pins 1,2,3,6 are need for data transmission. Two for transmission and two for reception. When two devices are to be connected (eg: machine to machine or Hub to Hub or Hub to switch etc:), the transmitted data from Device-1 shld reach the reception point of Device-2. So in the case of connecting 2 machines directly, where the connecting point is a Ethernet Card, the transmission and reception are set in the same way at both sides. At that time if we are using a straight thru cable, transmission data will reach the transmission point at the other end, instead if we are using a crossover cable (For a crossover cable, one end will be crimped normally and the other end will be crimped reverse, Tx will come to Rx and vice versa) transmitted data will end up at the reception point at the ethernet card and the link is established. There are Hubs with uplink port and without uplink port. For hubs without uplink port, if we want to cascade the same with a switch, we need to use a crossover cable, else connect a straight thru cable to uplink port of the Hub and connect it to the switch. I doubt if I've cleared ur doubt properly. Get to do some practicals with the same things, surely u'll come up with good results... > > I believe some serious networking help is required at my end. > > Regards and thanks > > Raghvendra NB: (Take care of necessary security.
